Description
BACKGROUND
1. Technical Field
The present disclosure relates to cable support assembly and more
particularly to a cable support assembly for use in connection with
a raised floor system.
2. Description of Related Art
Raised floor systems have been developed to provide the additional
utility space needed in various different conduit or cable
intensive environments where the original construction did not
provide adequate means of accommodating the vast amount of conduit
or cable. For example, probably the most common environment
requiring vast amounts of additional protected space is for large
computing systems. Such installations were typically made in
facilities which simply were not designed to accommodate the vast
amount of cable runs required to operate the typical large computer
system. Other applications where additional utility space is
required include mechanical systems, e.g., heating, ventilating and
air conditioning systems.
A common problem experienced in utilizing raised floor systems is
maintaining organization of the various cables, conduits, pipes,
etc. which are routed beneath the floor system. One solution to
this problem is to provide a cable tray system beneath the floor
panels of the raised floor to contain and direct cables along their
respective pathways. An example of such a cable tray system is
disclosed in U.S. Pat. No. 4,596,095 which issued on Jun. 24, 1986
to Chalfant (the "'095 Chalfant Patent"). The '095 Chalfant Patent
features a modular cable tray assembly which is formed from modular
sections which include a number of different components all of
which must be separately assembled to form the cable tray. For
example, the cable tray includes separate straight sections,
horizontal bend sections, horizontal tee sections, horizontal
cross-intersection sections, as well as splice plates to connect
the various components to each other as well as supporting the
assembled cable tray above the building floor. Such a cable tray
assembly is, therefore, independent of the raised floor system.
One drawback of such a raised floor and cable support system is the
additional labor required to assemble the various components of the
separate raised floor and cable support systems. In geographic
regions with particularly high labor rates, the cost of erecting
such a labor intensive dual system could prove to be cost
prohibitive.
Another drawback of such a system is that the amount of space
required by the structural supporting components of the two
separate systems leaves less space available for carrying and
organizing larger numbers of cable runs.
Yet another drawback of installing independent raised floor and
cable support systems is the cost of procuring the materials
required for two separate support structures. These additional
labor and material costs can significantly increase the overall
cost of installing a complete system.
An alternative solution to supporting cable runs below a raised
floor assembly is proposed in U.S. Pat. No. 5,548,932 which issued
on Aug. 27, 1996 to Mead (the "'932 Mead Patent"). The '932 Mead
Patent features a height adjustable cable tray support system which
includes a number of separate components which must be assembled to
form the cable support system. Plates which support the cable tray
are secured by welding or other methods to the pedestals of the
existing raised floor system featured in the '932 Mead Patent.
Additionally, support rods are required in the '932 Mead Patent
cable tray support system, which support the cable tray on the
support plates.
One disadvantage of such a system is the labor intensive nature of
the installation. In particular, each support plate must be
separately secured to the floor system pedestals and the support
rods and cable tray sections must be installed. This combined with
the cost of the material components required for such a system can
add significant cost to the installation of the complete
system.
Accordingly, there is a continuing need for improved raised floor
and cable management systems which require fewer number of
components. A need also exists for raised floor and cable
management systems which are easier to install than existing
systems and which provide increased storage capacity and
accessibility.
SUMMARY
The present disclosure provides a cable support assembly for a
raised floor system which overcomes the above-noted and other
disadvantages of existing raised floor and cable management
systems. Additionally, the present disclosure provides a cable
support assembly for raised floor systems which requires many fewer
components to assemble thereby resulting in greatly reduced
material and labor costs to install a complete raised floor and
cable management system or to upgrade an existing raised floor
system with the presently disclosed cable support assembly.
In one aspect of the present disclosure an intersection member is
provided for use in a raised floor system having a plurality of
support pedestals, a plurality of floor panels, and at least one
cable support apparatus wherein the intersection member includes a
cable support section, and connecting portions extending from the
cable support section, the connecting portions being configured and
dimensioned to retain the cable support section in place when
positioned at the intersection of at least two cable pathways.
The connecting portions may include downwardly oriented tip
portions which are configured and dimensioned to interact with a
cable support apparatus of a raised floor system such that the
intersection member is supported by the cable support apparatus. In
one embodiment, the intersection member is open-sided to form a "T"
shaped intersection. In an alternative embodiment, the intersection
member is generally planar to form a four-way intersection between
cable pathways.
In one aspect of the disclosure, the intersecting member may be
formed as a lattice work of intersecting members joined together.
In one particular configuration, the intersecting members may be
formed from wire stock.
The present disclosure further provides a hardware mounting
assembly for mounting hardware relative to a cable support
apparatus, which includes a bracket portion configured and
dimensioned to support various hardware components and position the
components relative to a cable support apparatus, and a plurality
of notches formed along the bracket portion, the notches being
configured and dimensioned to engage portions of the cable support
apparatus such that the bracket portion is maintained a
predetermined relative distance from the cable support
apparatus.
Preferably, the bracket portion is provided with preformed openings
therein to receive various hardware components. The hardware
mounting assembly may further include a transition portion
extending from the bracket portion such that transition portion
supports and directs cables when positioned thereon.
The present disclosure includes a cable support assembly for use
with a raised floor system having a plurality of support pedestals,
the cable support assembly including a plurality of cable support
apparatus each having at least one elongated stringer element being
supported a predetermined distance away from a base by a first pair
of a plurality of support pedestals and a channel section suspended
from the at least one elongated stringer element, the channel
section being configured and dimensioned to support lengths of
cable thereon, and at least one intersection member having a cable
support section and connecting portions extending from the cable
support section, the connecting portions being configured and
dimensioned to retain the cable support section in place when
positioned at the intersection of at least two cable pathways.
In a further embodiment, a cable support assembly is provided for
use with a raised floor system having a plurality of support
pedestals, the cable support assembly including, a plurality of
cable support apparatus each having at least one elongated stringer
element being supported a predetermined distance away from a base
by a first pair of a plurality of support pedestals and a channel
section suspended from the at least one elongated stringer element,
the channel section being configured and dimensioned to support
lengths of cable thereon, and a hardware support member including a
bracket portion configured and dimensioned to support various
hardware components and position the components relative to a cable
support apparatus and a plurality of notches formed along the
bracket portion, the notches being configured and dimensioned to
engage portions of the cable support apparatus such that the
bracket portion is maintained a predetermined relative distance
from the cable support apparatus.
In one aspect of the cable support assembly, a transition portion
is provided which extends from the bracket portion such that
transition portion supports and directs cables when positioned
thereon.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now in specific detail to the drawings in which like
reference numerals identify similar or identical elements
throughout the several views, and initially to FIG. 1, one
embodiment of a raised floor system constructed in accordance with
the present disclosure is shown generally as raised floor system
10.
Generally, raised floor system 10 includes a series of support
pedestals such as stanchions 12 which are disposed in a
predetermined array on a base such as floor 13. A cable support
assembly is provided in raised floor system 10 and includes a
series of cable support apparatus or sections such as cable baskets
14 which are disposed relative one another to form a predetermined
passageway for carrying cables or the like thereon. Preferably
cable baskets 14 form an integral part of floor system 10.
Stanchions 12 are interconnected by stringer members 16 so as to
define a lattice work which receives individual floor panels 18
therein to form the completed raised floor system 10.
In certain installations it may be desirable or necessary to
install the cable support assembly as a stand-alone modular
assembly. It is within the scope of the present disclosure, that in
such an installation, cable baskets 14 will be supported a
predetermined distance above the building floor 13 by independent
stanchions 12 or other suitable supports which are not also used to
support the raised floor system 10.
Referring now to FIG. 2, cable basket 14 includes first and second
elongated stringer elements 20 and 22, respectively. A channel
section is suspended from stringers 20 and 22 so as to form a
portion of a passageway for supporting cable runs thereon. In the
illustrated embodiment, the channel section is formed of an open
ended wire stock basket having longitudinal sections 26 attached to
transverse sections 24. Transverse sections 24 include riser
portions or legs 28 which are attached to the underside of
stringers 20 and 22. The various elements of cable support assembly
14 are preferably joined by suitable known techniques, such as by
welding.
Although the illustrated channel sections formed of wire stock
material, it is within the scope of the present disclosure to use
other materials as well. For example, the channel section may be
formed of solid or woven fabrications of various metals or any
other material suitable for supporting cable runs thereon.
Referring now to FIGS. 3-5, the integration of cable baskets 14
into raised floor system 10 will now be described in detail.
Preferably, a single section of cable basket 14 is supported by
four stanchions 12 (as shown in FIG. 1). However, it is within the
scope of the present disclosure that cable baskets 14 may be
modified so as to be supported by more or less than four stanchions
12.
As shown in FIG. 3, cable baskets 14 are supported by stanchions 12
such that the longitudinal and transverse elements 26 and 24
respectively are spaced a predetermined distance from the permanent
floor 13. When installed, cable baskets 14 do not interfere with
the placement or fit of floor panels 18. Rather, cable baskets 14
are designed to be incorporated into existing raised floor systems
without departing from the factory design specifications of the
floor system. For such installations, cable baskets 14 replace
parallel end to end links of stringers 16 from the existing raised
floor system.
As shown in FIG. 4, cable support assembly sections 14 include
stringer elements such as stringers 20 and 22 which have a cross
sectional "top hat" shape that includes an inverted U-shaped cross
section portion having flanges 32 and 34 formed on either side.
Horizontal surface 30 forms the uppermost surface of stringers 20
and 22. It is on surface 30 which a peripheral flange 36 formed on
floor panels 18 rests. As best illustrated in FIG. 5, the
peripheral flanges 36 of adjacent floor panels 18 are both
supported by a single stringer element 20 or 22 on surface 30. In
order to maintain the relative positioning of stringer elements 20
and 22 with respect to stanchion 12, stringer elements 20 and 22
are provided with notched portions 38 which are configured and
dimensioned to fit over bracket portions 40 of stanchion base plate
42.
Stringer elements 20 and 22 are further provided with preformed
holes 44 which when properly installed are vertically aligned with
preformed holes 46 formed in stanchion base plate 42. In this
manner, stringer elements 20 and 22 may be secured to stanchion 12
to provide added structural integrity to the overall system. As is
common in conventional floor systems, floor system 10 is preferably
provided with a high adjustment mechanism to adjust the t of
stanchion base plate 42 in order to accommodate slight variances in
the subfloor 13. This height adjustment capability may be
facilitated by, for example, threaded stud 48 being received in a
threaded bore 50 formed in base plate 42 at one end and in a
threaded opening of stanchion 12. A nut 52 is provided and is
threaded around stud 48 positioned adjacent the top of stanchion
tube to facilitate adjustment and locking of the vertical
positioning of base plate 42.
Referring to FIG. 6, an alternative method of attaching the cable
basket to the stringers is shown wherein cable basket 14 has
portions 14a and 14b which are formed extending outwardly from the
upper portions of riser legs 28. Stringers 120 and 122, which are
otherwise the same as stringers 20 and 22, are provided with a
series of through-holes 120a and 120b, respectively, which may be
punched out during formation of the stringers. In this manner,
cable basket 14 may be suspended from stringers by inserting leg
portions 14a and 14b in through-holes 120a and 120b. It is
envisioned that all of the stringers of a raised floor system may
be provided with through-holes similar to 120a and 120b so that a
cable support system may be installed at any time and placed
between any parallel rows of stringers having such support
holes.
Alternatively, in existing raised floor systems which do not
already have stringers with pre-formed cable basket receiving
holes, such as holes 120a and 120b, the stringers positioned where
it is desired to support a series of cable baskets 14 could be
replaced with stringers having the pre-formed holes.
Referring to FIG. 7, in another alternative embodiment for
suspending cable baskets 14 from stringers 20, angled brackets 21
are provided which have leg portions 21a and 21b. Leg portion 21a
includes a through hole (shown in phantom lines) which receives leg
portion 14a of cable basket 14. Leg portion 21b is bolted into the
channel formed in the underside of stringer 20 by an expanding
fastener such as wedge-bolt 25.
Referring to FIG. 8, in a still further alternative embodiment for
suspending cable baskets 14 from stringers 20, a series of clips 23
are positioned on stringers 20 by having leg portions 23a and 23b
rest upon flanges 32 and 34, respectively. Leg portions 14a of
baskets 14 are inserted into receiving holes formed in clips 23.
Thus, baskets 14 are suspended from clips 23. In this manner,
existing floor system stringers could be utilized to support the
added cable baskets defining the cable support assembly.
Referring to FIGS. 9-13, intersection transition members will now
be described in connection with the cable support system as
generally illustrated in FIG. 9. For purposes of clarity, not all
of the raised floor system components are shown. In particular, the
floor panels and some of the stringer elements are not shown so
that the cable pathways and intersections may be illustrated with
greater clarity. It should be understood, however, that the
features and elements described hereinafter are preferably utilized
with a complete raised floor system such as raised floor system 10
of FIG. 1. There may be, however, some applications where it may be
desirable or necessary to utilize the cable support assembly
described herein as a stand-alone structure without being part of a
raised floor system.
Referring to FIGS. 9-11, a "T-shaped" intersection of the cable
support assembly is shown wherein a special purpose open-sided
cable support section such as cable basket 114 is disposed at the
juncture of two perpendicular cable support assembly pathways which
are generally represented by the double-headed arrow "A" and arrow
"B". Cable support pathways "A" and "B" may be formed by assembling
cable basket sections 14 in perpendicular linear arrays and
supporting them on the matrix of stanchions 12 which form the
support structure for the raised floor system. Cable basket 114 may
also be arranged with two intersecting pathways to form an "L" or
"elbow" shaped intersection of the pathways.
Cable basket 114 is the same as cable baskets 14 on one side
thereof, having a stringer 120 attached to riser portions or legs
128 and is open on the other side where transverse sections 124
terminate in connecting portions such as downwardly turned tips
124a. Tips 124a extend over the~outermost transverse section 24 of
cable basket 14 which forms the last segment of pathway "B". In
this manner, cable basket 114 is supported on the open side by the
adjacent cable basket 14 of pathway "B" and in turn by stanchions
12 which are positioned on either side of pathway "B" immediately
adjacent the junction of cable baskets 14 and 114.
In an alternative arrangement, a series of cable baskets 114 are
arranged parallel to a first cable pathway formed by a series of
cable baskets 14. Downwardly turned tips 124a are extended over the
outermost longitudinal section 26 (FIG. 2) of cable basket 14,
instead of outermost transverse section 24. In this manner a second
cable pathway is formed parallel to that formed by the series of
cable baskets 14.
Referring to FIGS. 12 and 13, a cross or four-way type intersection
of cable pathways is illustrated wherein two pathways intersect
perpendicularly and are designated generally by double headed
arrows "C" and "D", FIG. 12. To facilitate a smooth intersection
while maintaining support for cable runs placed in the pathways, a
four-way junction member 214 is provided. Junction member 214 is
formed from a lattice work of wire stock members which are joined
together by any suitable techniques such as for example, welding.
The ends of at least some of transverse and longitudinal sections
224 and 226 are provided with connecting portions such as
downwardly turned tips 224a and 226a respectively. Tips 224a and
226a serve to retain junction member 214 in place when it is
positioned at the intersection of pathways "C" and "D", in the same
manner as the open side of cable basket 114 as described above.
Referring to FIGS. 14-20 various embodiments of hardware mounting
assemblies for mounting hardware relative to the cable support
assembly will now be described in connection with the several
drawings. A first embodiment of a hardware mounting assembly is
shown in FIGS. 14 and 15 and includes a mounting bracket 228 having
a series of attachment notches 230 formed along a pair of vertical
side panels 232 and 234. Notches 230 facilitate attaching bracket
228 to the cable support assembly. Bracket 228 may be formed from
sheet metal which is stamped into blanks and subsequently formed by
suitable known techniques.
Notches 230 are preferably spaced apart so that each notch 230 is
aligned with a corresponding transverse element 24 or longitudinal
element 26 depending upon the orientation desired for attaching
bracket 228 to a particular cable basket section 14. Notches 230
may be in the form of a "bayonet" style such that they are aligned
above the corresponding transverse or longitudinal elements 24, 26,
respectively and bracket 228 is lowered into place and then shifted
so that transverse element 24 (as shown in FIG. 15) is fully
inserted in notch 230. In this manner, various hardware components
may be attached to bracket 228 as desired. For example, a
conventional patch block such as patch block 236 may be mounted in
a preformed opening on bracket 228.
Although bracket 228 is shown mounted to the upper side of the
cable support assembly, it may also be mounted to the underside of
the cable support assembly using the technique described above. For
example, as shown in FIGS. 16 and 17, a mounting bracket 328 is
mounted to the underside of a cable basket section 314 of a cable
support assembly. Bracket 328 is similar to bracket 228 except that
an opening is formed in the side vertical wall portion 332 to
facilitate mounting of a hardware element such as patch block
336.
Referring to FIG. 18, bracket 328 is shown mounted to a different
style cable support apparatus such as flexible cable support
apparatus 360 which unlike cable basket section 314, includes only
transverse cable support segments 362. Bracket 328 may be formed in
numerous different sizes to suit particular cable support
apparatus.
Referring to FIGS. 19 and 20 a further alternative embodiment of a
hardware support bracket is shown. Hardware support bracket 428 is
similar to brackets 228 and 328 and further includes a transition
portion such as ramp portion 438 which serves to support and direct
cables which are desired to be led into bracket 428 to be connected
to hardware elements mounted to the bracket, for example a patch
block (not shown). Ramp 438 may be stamped as part of a blank from
sheet metal which forms bracket 428 and subsequently bent to form
the desired ramp contour. Notches similar to notches 430 may be
formed on ramp 438 to facilitate attachment to a cable support
assembly element such as cable basket section 14. Side walls 440
may be formed as well as tab portions 442 along ramp 438 to
facilitate retention of cables by ramp 438.
Although the illustrative embodiments of the present disclosure
have been described herein with reference to the accompanying
drawings, it is to be understood that the disclosure is not limited
to those precise embodiments, and that various other changes and
modifications may be affected therein by one skilled in the art
without departing from the scope or spirit of the appended claims
or the disclosure.
